Abstract (en)

[origin: EP0644691A2] The video signal input is converted to high-speed reproduction data by a high-speed reproduction data encoder 1. The video signal input is converted to high-speed reproduction data by a formatter 2, which formats the high-speed reproduction data so that the same data is recorded to n tracks; this becomes the recorded data. After the recorded data is input to an error correction encoder 3, it is decoded by a decoder 4 and recorded by a recording head 5 to the magnetic tape 6. During reproduction, the recorded data is reproduced by reproduction head 7 from the magnetic tape 6, and decoded by decoder 8. The decoded data is then error corrected by an error correction decoder 9, and then input to a deformatter 10. The deformatter 10 separates the normal reproduction data from the high-speed reproduction data, and separately outputs both data types. During normal reproduction, the normal reproduction data is output by a switch 13; the high-speed reproduction data is decoded to video data by a high-speed reproduction data decoder during high speed reproduction, and output. <IMAGE>
